What's got me surprised is that with all this talk of detonation, my current setup never knocked, and that was with a set of fuelie heads, which I would have to imagine were more detonation prone than a set of Vortec heads.

Mar 13, 4. Messages: Likes Received: 1. The Vortecs have a very efficient chamber design that only requires degrees total timing. That means they are much less detonation prone than an older head. I would use the Felpro gaskets with 2 coats of copper spray. Mar 13, 5. I'm a bit hesitant to use steel gaskets because I'm not decking the block or resurfacing the heads. GM has some composite. If I'm not detonating with my s, then am I at risk with the vortecs?

Mar 13, 6. I would think the older stuff with bigger chambers would be less prone to knocking Anyways, I had a block that was decked years ago, I ran s with std head gaskets for years before I swapped over to. Not alot of miles on the old setup so I guess I was good to go without needing anything decked. Mar 13, 7. Most of the time the only thing you have to do is run a fine file or a stone like this.

Ls springs on Vortec heads? Here's what you need...

The deck get pulled up slightly around the bolt holes and this removes the high spots. I've used shim gaskets on a lot of motors so did the factory. They are a lot more forgiving than people think as long as you remove the high spots around the bolt holes. Mar 13, 8. Mar 13, 9. Short answer, no. Keep the timing at The chamber shape plus the proper quench distance will work better at preventing detonation than the old heads.

And we haven't even talked about the power increase you'll see. Those heads out power any other factory head that came before them. Mar 14, That's exactly why I'm making the swap. I'm hoping the Vortecs will give me some more horsepower, and a much better response under 3k.Register or Log In To remove these advertisements. Web chevytrucks.

I am working on a parts list for my stock goodwrench horse I am planning on a economy head and cam swap. I have a set of vortec heads with stock springs and a edelbrock manifold.

I tried different things, got a private blender, and started selling an additive to owner-operators at truck stops. After I found a secret ingredient, it sold so well that I had to decide whether to keep the trucking business going or go into the oil business.

Gotta love that secret ingredient, huh? I read another article saying that Mr.

There are still rodders interested in budget-based small-block Chevy stories and this one deserves updating. For those who may be new to the game, the Vortec head was first introduced on the L31 ci truck engines in Despite their journeyman use, these heads flow dramatically better than any other small-block Chevy production head, which makes them popular with just about anybody who wants to build a mild street small-block.

Used Vortecs are still around or you can purchase these castings brand new from Chevrolet Performance. While these heads will bolt right on a small-block Chevy, there are several caveats that you should be aware of before you torque those head bolts down.

Next, the Vortec head employs a small, 64cc combustion chamber. This is great for stock short block engines like the Chevrolet Performance hp crate engine that uses a dished piston with a 76cc combustion chamber head. That creates an 8. With a common, four-eyebrow flat top piston and a. There are other, smaller points that are important to know because they affect cam selection.

If you intend to run a very mild cam with less than 0. But today, even a stone stock 5. The stock Vortec iron head will not tolerate more than 0. We measured our stock iron heads right out of the box and the retainer-to-seal clearance was only 0. Subtract the standard 0. Just get out your tools and make some modifications.

The Vortec head features a very large boss at the base of the valve guide that measures 0.

The head uses 0. This guide boss is also very tall. This height restricts the room between the top of the seal and the bottom of the valve spring retainer at max valve lift. There are two simple approaches to modifying the head to accept a performance valve spring that will create the room necessary to allow greater valve lift. The easiest solution is also the most expensive. COMP Cams builds a beehive style valve spring that drops right in place of the stock spring along with new retainers and valve locks.Small block Chevy heads have been manufactured sinceand have been used in high performance applications as soon as the first one rolled off the assembly line.

Fifty-five years of manufacturing have left us with an endless number of different cylinder heads for the SBC engines.

General Motors estimated that throughmore than 90 million small block Chevys have been produced, which means that there have been at least that same number of SBC cylinder heads produced.

Add in the amount of high performance heads that GM Performance Parts have sold over the counter and the number is astronomical. Vortec debate! Read on! The GM small block was specifically designed as a compact sized engine to embrace the economical use of iron and to streamline the production process. Part of the design process that was carried through to the Gen III design in was to create lightweight rocker arms for higher rpm operation, wedge combustion chambers for a broader power band, and deliver 4.

Featuring the famous double hump marking on the ends of the heads, the and X heads used 1. The only difference between the two casting numbers was that the featured cc intake port, 62cc exhaust port and the X had the larger cc intake port, 64cc exhaust port.

The double hump heads continued to be a favorite with performance minded enthusiasts into the new millennium. High performance enthusiasts separated the stock Gen I heads into closed chamber and open chamber heads. By far, the closed chamber factory heads were favored over the open chamber for making power due to the poor burn characteristics and no swirl quench inside the combustion chamber of the open chamber heads. Furthermore, the cylinder heads that were capable of making decent power were all manufactured when lead was prevalent in fuel and the valve seats stayed lubricated.

Unless you were using leaded racing gasoline, the valve seats needed to be replaced with hardened valve seat inserts. By the time a racer was done modifying the heads, there was substantial monetary resources invested in the cylinder heads and it was hard to justify the modifications unless you were running in a class that dictated hardened valve seats in a cast iron head.

Available on the LT1 engine and over the counter. Either straight or angled plugs. Don McBride of McBride Performance Engine and Machining in Lake Elsinore, California, still prefers the old school cast heads because his shop specializes in building engines for circle track racing and desert racing.

You have room to manipulate and improve the flow on these heads. Of course we still have to build the engines according to the rules of the tracks that our customers are running at, and for the most part, the old style heads are what they are mandated to use by the rules.

The newer style Vortec heads have a lot cleaner castings, however. Because of the extra metal, the old style heads seem to be less prone to heating problems, and circle track engines get pretty hot.

The Phase II was the most popular for hot rodders and featured a cc intake port volume, and 64cc combustion chamber. The biggest change GM made in the new design was revising the water jacket so the new Vortec heads could be used on conventionally cooled small blocks. The idea of using the LT1 cast iron head as a starting point for a new performance stock head came from the fact that it was the highest flowing LT head used by GM.

The cast iron Vortec head was in development six months longer than the aluminum head, and during that time, GM engineers tweaked the intake and exhaust ports for additional flow. The cast iron Vortec heads was one of the first to purposely integrate tumble instead of large swirl numbers in the design. The newly redesigned Vortec cylinder heads were intended to replace the swirl-port Throttle Body Injection heads that were previously used on GM trucks.

What got the power merchants attention was the increase in horsepower from to solely based on the power generated by these heads. By the time you purchased a used double hump cylinder head and had it reworked, the cost was the same as buying a new Vortec head that produced more power. Circle track racers were tossing their double hump heads as fast as they could buy the new Vortec heads.

On the non-bow tie L31 Vortec heads, the ports are larger than the older cast steel heads, so they outflow the older heads. The L31 Vortec comes in two different casting numbers, or Register or Log In To remove these advertisements.

The torque on the manifold bolt is important for sealing. If you have a Chilton or Haynes manual, follow the procedure for the Vortec intakes. Well, I found a motor with k on it and it needs valve stem seals. Would it be a bad idea to put this setup on the top end? Will the bottom end blow out? BWOOD that is perfect. Thank you Let me know. The increase in power will not be so drastic that it would do that kind of damage. But it may be worth the time to pull the pan and maybe a few bearings and use some plastigauge and check the wear.

If the wear is bad I would suggest a different engine or freshen that one up with rings, bearings, gaskets, oil pump and maybe a cam I don't mean aftermarket, just a new stocker or step up to the roller setup like in the Vortecs.

You say it needs stem seals now, so I assume it is burning some oil, I would make sure that is the only issue with the engine. You might concider finding a lower mileage Vortec block and use it. It will also work and will have the roller cam and the heads installed. I have a 93 burb and it has just a plain old 5.

I had to rev the hell out of the truck to get any power? I am going with a or a BBC next. I ran a compression test and pulled all the main and rod bearings and checked them with plasti guage, installed a new oil pump and timing chain before the install.

I guess I needed a rev limiter set to something less than 6k. It rev'ed great? Originally Posted by mongoose. Reason: spelling.If you are an international customer who ships to a US address choose "United States delivery" and we will estimate your ship dates accordingly.
